bienchen's mod is great. Since getting it I have yet to see a female sim with body hair. But I have had it show up on one male sim. I need to make sure I don't have a mod conflict though. I think there is another new mod that does it by gender and that one may be why the one male sim had it.
No idea why this wasn't a feature you could toggle on/off by a combo of things like gender, age, hairstyle, and even occult type...
I'd even love the ability to toggle it off by whatever flags sims to be of one ethnicity or another. Native American, Asian, and some Polynesian sims should have a lot less to none of it. I know they (somewhat) track a sim's ethnicity because it shows up in consistent patterns for eyes, names, noses, hair and skin tones - so this one should have gone into that system as well. Sure that system has frequent flaws like red haired Asians and blond Africans (both of which happen in RL among a small subset of mixed people) - but it gets it right about half the time which is still way above never.
